3 Claims.

This invention relates to detachable hammer tips and the principalobject of the invention resides in the provision of a new and improveddetachable soft tip or head for hammers so as to provide a soft strikingelement for a conventional hammer.

Further objects of the invention reside in the provision of a relativelysoft striking element or core surrounded by a ring which embodies meansfor detachably securing the same to the striking face of the hammer,said ring tightly fitting the soft striking element and preventing thesame from being distorted outwardly under impact; and the provision of ashouldered soft striking element in combination with means fordetachably securing the same to a hammer head, said means being disposedon said shoulder and maintained thereon by means of a ring surroundingthe soft striking element and maintaining the same in position as aunit.

Further objects of the invention reside in the provision of a device asabove described and including resilient means holding the same to ahammer head, said resilient means providing easy attachment anddetachment thereof while, at the same time, firmly holding the same instriking position on the hammer.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings in which Fig. 1 is aview in side elevation of the hammer attachment in position on thehammer, parts being in section;

Fig. 2 is a view in side elevation of the attachment; and

Fig. 3 is a view in front elevation thereof.

As shown in Fig. 1 there is provided a conventional hammer head l havinga handle l2 and a striking element or head of conventional designindicated at I4. The invention resides in an attachable and detachablestriking element which will be secured to the striking element of thehammer in such a way that it provides a soft striker for the hammerwhich is quick and easy to attach and detach and which obviates the useof a separate plastic, leather, or soft metal hammer.

A cylindrical soft striking element or core I6 is provided with arounded face as at [8 to provide for dead center hammering and anintegral flange 20 providing a shoulder. The soft element i6 has a planerear surface 22 for contact with the rounded striking face surface ofthe hammer element M.

Disposed on the shoulder formed by flange 20' there are a plurality ofarcuate spring fingers 24 which extend to the rear and terminate inreversely bent elements 26 forming a funnel-like conformation for easyattachment to the hammer head M. A split ring 28 surrounds the resilientfingers to insure the holding power thereof behind the hammer head M.

A steel or the like ring 30 closely fits both the spring fingers and theflange 20 as well as the periphery of the striking element [6 as at 32,by means of a flange 34, and it is to be understood that the elements16, 30, and 24 provide together a permanently secured integral unit asshown in Fig. 2.

The soft striking element comprising the part IS, the ring 30, thespring fingers 24, and the split ring 28 is easily slipped on and offthe hammer head [4 but, at the same time, is held tightly thereon by thespring fingers in the ring 28 so that the invention provides anefficient yet inexpensive soft hammer head for use wherever soft hammersare needed; and it is also to be understood that the material of whichthe element i6 is made may be any material convenient or desired to beused without departing from the scope of the invention.

In use of the device, the soft core or striking element l6 will tend tospread, but excess of distortion is prevented by the ring 30, and thecore will be more tightly held to the ring. Regardless of spreading ordistortion of core [6, however, the fingers 24 will always firmly holdthe device, to the hammer, the spring finger construction and split ring28 allowing for some degree of flattening of the core flange 20, whichwill be small, most of the core distortion occurring in the exposedportion of the core.

Having thus described my invention and the advantages thereof, I do notwish to be limited to the details herein disclosed otherwise than as setforth in the claims, but what I claim is:

l. A device of the class described comprising a shouldered ring, acooperatively shouldered relatively soft core extending therefrom, saidring tightly fitting the core, and means to detachably secure the deviceto the head of a hammer, said means comprising separate spring fingers,a flange at the end of each finger, the flanges being inserted betweenthe core and ring shoulders and thereby held to the device.

2. A device of the class described comprising a flanged ring, a flangedsoft core, the core being located in the ring with the flanges insubstantial contact preventing movement of the core rela- RENCES CITEDtive to the ring in one direction, separate spring The fonowingreferences are of rd 1 th fi n g ers to secure the device to a hammerhead, file of thi patent;
